In the depression years of the 1930's many unemployed men travelled
about
the country in search of whatever work they could find. Freight trains
provided a means of transportation.

Through dangerous and uncomfortable and actively discouraged by railway
police,
there was no fare to pay. On a pleasant moonlit evening, three travellers
settle around a campfire as a train rumbles across a coulee on a wooden trestle.
A walk into town in the morning may result in a few hours of work or an
outbound
freight may carry them to another place and another campfire.
